NORWICH CITY VS SOUTHAMPTONNorwich have won two of their last three, as many games as they did in their previous 14 combined. Southampton, who were fourth at this stage of last season, have won just twice away from home so far this season, scoring only nine goals. But Norwich have only 11 goals at home.SUNDERLAND VS ASTON VILLAAston Villa have kept just one clean sheet in their last 18 league games, and since their only win, at Bournemouth, they have taken two points in nine games on the road. Sunderland are 19th and just four points ahead of bottom-placed Villa after losing, on Wednesday, against Liverpool, their fifth loss in a row.WEST BROM VSSTOKE CITYStoke have conceded 19 goals this season – only four sides have leaked fewer. And the Potters are four points better off than at the halfway stage last season. In August Stoke had midfielders Ibrahim Afellay and Charlie Adam sent off as West Brom secured a first league win this season.WEST HAM VSLIVERPOOLWest Ham are unbeaten in six games in the Barclays Premier League, though five of those have been drawn. Liverpool won 1-0 at Sunderland on Wednesday to move above the Hammers, into seventh place. West Ham’s Andy Carroll, the match winner against Southampton on Monday, could start against his former club.CRYSTAL PALACE VS CHELSEAAt this stage last season Chelsea led the Premier League comfortably, with 14 wins from 19 games and just one loss, helping the Blues to 46 points. Now, at the halfway stage the Blues have won just five games and accrued 20 points. In addition they have 23 goals compared to 41 last term.
© 2012 Phys.Org Image: USPTO, number 0910660.0 What this means is that Sony is planning to resolve the disadvantages of no-glasses 3-D viewing in the home. Critics have often noted blurring and other compromised effects that make the 3-D viewing experience less than desired just because the viewer is not in the best position. The success of autostereoscopic (glasses-free) 3-D has depended highly on the viewer’s angle and distance from the screen. With Sony’s 3-D viewing concept, the application would be able to detect a user’s distance from the screen and adjust the separation of images accordingly.Sony points out past technology limitations of 3-D viewing with no glasses in its patent: “3-D content is recorded using a stereoscopic camera having a fixed arrangement of lenses that presuppose a corresponding fixed viewing position.” The problem, says Sony, is that the effect of being in the wrong place for viewing is discouraging. According to the patent, “the reproduced image can feel unnatural and in extreme cases may lead to headaches or nausea.” Sony says one particular weakness is under- or over-exaggeration of depth, depending on how near or far the user is from the screen.The patent is for both an image-processing method and an entertainment system for the image display. The patent says that Sony’s technology involves shifting image elements in at least one of the left-eye and right-eye images to change the size of displacements, as a function of existing displacements, and the point of intersection of lines of sight between the corresponding image elements and the viewer. The separation in depth between different image elements is substantially the same as it would have been if the user had been viewing the video at the ideal distance.Sony’s patent does not represent the first attempt of a company seeking to evolve non-glasses 3-D viewing. Cebit in 2010 in Hanover, Germany, is a case in point. Technology companies at Cebit created a stir showing efforts toward a new breed of displays. Sunny Ocean Studios had a panel fitted to a standard display, sending out a stereoscopic image to 64 positions around the screen. That meant you would be able to “run around” and see a nice 3D display, said Armin Grasnick of Sunny Ocean, at the time. Another company, SeeFront, showed a display moving with the viewer’s eyes, with the viewer always seeing the 3-D image. Eye-tracking has been an essential component of its glasses-free 3-D display technology, according to SeeFront.

In its application, “Stereoscopic Image Processing Method and Apparatus,” Sony defined its patent intent: “A stereoscopic image processing method for a stereoscopic image pair forming a 3-D image comprises the steps of evaluating whether the distance of a user is closer or further than a preferred distance from a 3-D image display upon which the stereoscopic image pair is to be displayed, and if the evaluation indicates that the user is further than the preferred distance from the 3-D image display, adjusting the respective displacements between corresponding image elements in the stereoscopic image pair, thereby changing the stereoscopic parallax in the 3-D image.” Apple patents an inexpensive 3-D projection system This document is subject to copyright.
